ALFRED Gr. NORDMARKEN, F MINNEAPOLIS, MINNESOTA ASSIGNOR 'I'O HIDE-AWAY SCREEN COMPANY, A CORPORATION OF WISCONSIN WINDOW SCREEN Application filed April 11,

My invention relates to window screens, and particularly to window screens adapted to be used for doublehungwindows, and has for its object to providea window screen which may be, entirely enclosed upon the closing of V the window, to conceal said screen, and which may be broughtinto operative position upon the opening, of the window.

Another object of the invention resides in 1a attaching the screen at one end to a spring actuated roller, and in mounting the roller within a groove formed either in the rail of the window vsash or in the frame thereof, and in, attaching the screen at its other end to the opposite portion of the frame or sash.

Another object of the inventionresides in forming the groove in one of the edges of the sash moving from or toward the frame, said groove being adapted to be closed by the frame when the window is in closed position to completely enclose the screen within the groove and conceal the screen.

Another object of the invention resides in disposing said grooves and screen adjacent the stop,.parting strip or other guide for the window sash so as to bringthe screen in close proximity thereto to tightly close the opening formed in the window.

Other objects of the invention reside in the details of construction thereof, and in the novel combination and arrangement of parts hereinafter illustrated or described. In the drawings: Fig. 1 is an elevational-view of a double hung windowsillustrating an embodiment of my invention. Q 1

In the use of window screens, a considerable amount of light is excluded when the usual screen is applied 1 to the window, and particularly where afull size screen is used. In addition, dirt and dust readily accumulate on the screen and upon the. exterior of the window, and access to the exterior of the window is precluded, causing the window to remain dirty during the time that the screen is in place within the window frame. My invention overcomes these difficulties by providing a window screen adapted to be completely enclosed when the window is in closed position, and which serves to close the open,- ingformed bythe window when the same is open.

F or the purpose of illustrating an application of my invention, Ihave shown. in the drawings an ordinary double hung window, which is indicated in its entirety at A. This window comprises a window frame 10, an uppersash 11, and a lower sash12. .These parts maybe constructed in any of the usual ways, the particular form illustrated being shown merely for the purpose of indicating the ,method of applying my invention thereto.

7 The frame 10 consists of vertical frame members 13 connected together at theirupper ends by means of a header 1& and at their lower end by means ofthe usual window sill 15. The frame 10 is set into the opening of the building and is attached to the studding 16 thereof in the usual manner. Frame 10 may be constructedwith an outer casing 17 and an inner casing 1 8, and is provided with the usual inner stop 19, outer stop 20, and parting strip 21. The window. illustrated also includes the usual stool 22 and apron 28, .associatedwith the interior casing 18.

The two sash 11 and 12 are similarly. constructed. The sash 11 is formed with stiles 24, and upper rail 25, and a parting rail 26,

while the sash 12 is similarly formed with stiles 27, a parting rail 28 and a lower rail 29. These stiles and rails are recessed to receive the usual window panes 30 and 31 which may be mounted therein in the usual manner and sealed through the use of putty or a similar means. T he upper sash 11 is slidably mounted between the outer stop 20 and the parting strip 21, while the lower sash 12 is slidably mounted between the said parting strip and the inner stop 19. lVhen the sash are in closed position, the rails 25 and 29 are received within the respective stops and parting strips and the stool 22, and the meeting rails of the sash adjoin one another to completely close the window in the usual manner.

The screen proper used in conjunction with my invention is preferably of fabric or flexible wire, and is coiled about a suitable roller and attached at one end thereto. If desired, screens may be utilized for both the upper and lower sash, or for only one of these sash, as the occasion demands. In the drawings, I hav e shown a screen 40 in conjunction with the lower sash, and a screen 41 used in conjunction with the upper sash. Since both of these screens are identical in construction and mounted in the same manner, only the screen 40 will be described in detail.

The particular roller to which the screen 40 is attached is best shown in detail in Fig. 3. This roller is indicated at 33 and is con structed similar to the ordinary shade roller used with window shades. This roller is formed at one end with a bore 34 which extends partially throughout the same. Within this bore is disposed a rod 35 which has coiled about it a helical spring 36 attached at one end to the roll-er 33, and at the other end to said rod. The rod 35 has mounted on it a plate 36 which forms a bearing for a lug 38 issuing outwardly from said rod and fixedly secured thereto. The plate 37 is held attached to the end of the roller 33 by means of a ferrule 39 which is clinched in place thereon.

For the purpose of the invention, the lower rail 29 of the sash 12 is formed with a groove 42 extending along the entire width thereof and up into the said rail proper. This groove is of a size large enough to receive the roller 33 with the screen 40 completely wound thereon. The roller 33 is mounted for rotation within the groove 42 through two end plates 44 which are attached to the rail 29 and which are formed with recesses 45 adapted to receive the lug 38 and a similar circular lug positioned at the other end of the roller. These plates, in addition to closing the end of the groove 42, serve to rotatably support the roller 33, which is journalled upon the opposite lug and upon the plate 3?. The roller 33 is not constructed with the usual pawl employed. with shade rollers,'so that the screen 40 is automatically wound or unwound as the tension on the same is varied. It will be noted that the metal of the plate 44 is pressed inwardly into the end of the roller 33 to bring the outer portion thereof as close to the edges of the window as possible, which brings the screen 40 close to the edge of the window.

From an inspection of 2, it will be noted that screen 40 is wound on the roller 33 in such a manner as to lie adjacent the parting strip 21 when the screen is properly mounted. The lower end 46 of screen 40 is attached to the sill 15 of the window frame 10 by means of screws 47 or other suitable fastening members. As the lower sash 12 is raised, the screen 40 is unwound from the roller 33 and closes the opening formed be-' tween said sash and the frame proper. lVhen so disposed, the edges of the screen lie close to the parting strip 21 to completely close the opening of the window.

'As before stated, the window 30 may be similarly provided with a screen 41 which is positioned adjacent the stop 20 and attached to the header 14 of the frame member 10 in exactly the same manner as the screen member 40. This screen is also mounted upon a suitable roller 33 received within a groove '48 in the rail 25 of sash 11. By means of this construction, either the upper or the lower sash may be raised or lowered to open the window and when so raised or lowered, the screens 40 and 41 cover the openings formed in the Window. \Vhen the sash 11 and 12 are brought into closing position, the springs 36 wind the screen upon the respective roller 33 causing the said screens to disappear when the window is completely closed.

For the purpose of effecting a closure be tween the two sash 11 and 12, when the same are in open position, a sealing strip 49 is employed which is attached to the meeting rail 26 of the sash 11. This strip projects over toward the window pane 31 and serves to maintain the space between the said sash closed while the sash are in open position.

In the construction of the invention, the screens 40 and 41 may be made of fabric, wire or any other suitable flexible material adapted to be rolled upon the supporting roller. If desired, the end portion of the screen may be formed more closely wo'ven than the remainder thereof, or of different materials, or one or the other of the screens constructed entirely in such manner. \Vhen so con.- structed', the closely woven portion is first exposed upon opening the window and the remainder thereafter. The closely woven portion of the screen when so used. serves, in the winter time, to prevent drafts, and to exclude the snow from the interior of the room in which the invention is employed. In a screen so constructed, full circulation of air through the same may be had by raising the window its entire height.

In Fig. 4, I have shown a modification of my invention. lVhere the rail of the sash is narrow or where the diameter of the roller with the screen thereon is fairly large, it becomes frequently impossible to install the same within a groove formed in the rail of the window. In such case, a device, such as shown in Fig. l, may be employed. In this figure, I have shown the rail 51 of a sash 52 which is formed with a rabbet 53 along the outer portion of the lower edge thereof. This rabbet is closed at the outer edge by means of an angular strip of metal 5a which is provided with a flange 55 attached to the rail 51 at the lower portion of said rabbet. By the use of the strip 54:, the groove formed between the rabbet 53 and said strip which is used for the reception of the screen roller may be constructed considerably 1 larger than that formed by grooving the rail proper. This permits of receiving a roller 56 of considerably larger diameter than the roller 33 or of installing a roller, such as 33, ina sash of less thickness.

. My invention is highly advantageous in that a simple and effective device is provided whereby the opening formed through a double hung window may be readily covered to exclude vermin and other foreign matter not desired within the interior of the building with which the screen is utilized. When the window is closed, the screen completely disappears, giving the window an attractive appearance and transmitting a maximum amount of light through the same. The screen of my invention may be allowed to remain attached to the window throughout the entire year, and is equally as useful in summer as in winter. The screen does not interfere with the washing of thewindows from either side and may be left in place even with the application of storm windows to the same. When it is desired to remove the screen, the same may be accomplished from the interior of the building thereby eliminating ladders and the inconvenience of removal of the same from the exterior.

Changes in the specific form of my invention, as herein disclosed, may be made within the scope of what is claimed without departing from the spirit of my invention.

Having described my invention, what I claim as new and desire to protect by Letters Patent is:

1. In combination with a rail of a window sash having a rabbet at the outer corner thereof adapted to house a screen roller, said rabbet opening outwardly and downwardly to leave the inner face of the sash rail intact, said rail having an outwardly facing recess above said rabbet and a metal plate bet having a longitudinal opening facing said stop, a metal plate extending along said rail and closing said opening, one side of said plate riding along said stop, said rabbet being adapted to house a roller having a screen wound thereon to pay off the roller adjacent the other side of said plate and in close proximity to said stop.

In testimony whereof I have afiixed my signature to this specification.
